.F ENCE-POST.

QPECIPICAIION forming part of Letters Patent No. 345,075, dated July 6,1886.

Application filed September 16, 1885. Serial No. 177.249. (N0 model.)

To aZZ whom it may concern:

Be itknownthat I, J AY L. QUAOKENBUSH, of Portland, in the county ofMultnomah and State of Oregon, have invented a new and ImprovedFence-Post, of which the following is a full, clear, and exactdescription.

My invention relates to metal posts for fences, and has for its objectto promote the stability of the posts,and also to provide a post that islight, strong, durable, and inexpensive,

and which shall give substantial support to the fence-wires.

The invention consists in certain novel features of construction andcombinations of parts of the fence-post, all as hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of referenceindicatecorresponding parts in all the figures.

Figure 1 is a side elevation of myimproved fence post as set into theground. Fig. 2 is a plan view of the screw ground-plate. Fig. 3 showsthe lower end of the post with a surface ground-plate applied. Fig. 4 isa plan view of the surface ground-plate, and Fig. 5 is a cross-sectionof the upper part of the fence-post.

The fence-post is made with a bar, 'A,ofplatemetal, which is rolled,pressed, or cast at its upper or above-ground portion in concavoconvexform, as at a, and with aflange, (1, along one edge; but the bar mayhave a flange along its other edge also, as indicated by the dottedlines at a in Fig. 5. The lower or embedded part of the post-bar A isformed into a screw, B, which is tapering, and is pointed like a gimlet,so as to enter the ground easily, and the screw is sharpened all alongthe periphery of its thread, so that it will not lift the earth much, ifany, but will compress the earth tightly around the threads, to make amore secure fastening for the post in the ground by the screw than woulda screw having a blunt peripheral edge, or otherwise shaped so it wouldlift the earth considerably and force it away from the threads.

The letter 0 indicates a ground-pl ate,which is made separate from thebar A,and of metal, and in helical form, so as to constitute about onecomplete turn of a screw, the forward edge,

a, of which is sharpened,so that after the plate until the plate 0 restsby its entire under face on the ground-surface,0r until the entire plateis embedded in the ground,asshown in Fig. 1. The peripheral edge 0 ofthe helical groundplate 0 is sharpened, so that the plate lifts theearth little or none, and packs the earth solidly about it, to make astrong and reliable anchor to the upright part A B of the post. Thecentral aperture, 1), of the plate 0 is elongated, and the oppositemarginal portions, b b*, of the plate at the aperture b are shaped toform a nut corresponding with the thread of the screw B, so that thepost-bar A B cannot be drawn from the embedded ground-plate C,but mustbe unscrewed to remove it therefrom. The flange a of the post-bar A isnotched or slotted angularly, as at E, and the fence-wires F are passedone into each of the notches,and the tongues or points 6 of the flangethen are hammered across the notches, so as to bind the wires'F tightlytherein and to the post, as shown at e in Fig. 1. \Vood or metal stripsmay be woven into the wires between the posts as a warning to persons orstock that they are approaching a barrier and to prevent sagging of thewires.

In Figs. 3 and 4 the ground-plate G,instead of being made helical toscrew into the ground like the plate 0, above described,is made inconcavo-convex form,and has a central elongated aperture, b,with marginsb b", shaped to form a nut for allowing the plate to be screwed on thepost-bar A as far as it will go,and then the end B of the post will bescrewed into the ground D until the concaved lower face ofthe plate 0 isdrawn down on and into the ground sufficiently to cause the earth tofill and pack hard into the concavity of the plate, asin Fig. 3,wherebythe air will partially be expelled from below the plate, and theair-pressure on top of the plate assists the screw B and the actualbearing of the under sideof the plate on the ground to hold the posterect and firmly to place.

It is evident that. the concavo-convex crosssectional form of the part aof the postbar A gives the post great strength,and the method ofsecuring the fence-wires in the flange a is very simple and eifective,and that whichever of the ground-plates C or C be used the posts willstand firmly to give substantial support to the fence-wires.Furthermore, the entire fence-post is very light, strong, and durable,and maybe made at a low cost.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 1. The combination, in a fence-post, of a post-bar,A, provided with a tapering screw, B, at its lower end, and a separablegroundplate, 0, having an aperture, b, marginally shaped at b b,substantially as shown and described, whereby the ground-plate may bescrewed on the post-bar and the post-bar then screwed into the ground,toclamp the groundplate thereto for steadying the post, as set forth.

2. The combination, in a fence-post, of a post-bar, A, provided with atapering screw,

B, at its lower eud, and a separable groundbar, A, provided with aflange, as at u, hav-' ing slots E, and having a tapering screw,B,at itslower end, and a separable ground-plate, 0, having anaperture,b,marginally shaped as at b b, substantially as herein shownand described, and for the purposes set forth.
